  • Power amplifying system with supply and bias enhancements
    Patent number: 6784748
    Abstract: A radio frequency (RF) power amplifying system. The power amplifying system includes a power controller and power amplifiers comprising power transistors and bias circuitry. The bias circuitry provides current to the base of the one or more power transistors in such as manner as to automatically maintain the power transistors in substantially linear operation throughout the variation in voltage as supplied by the power controller.
    Type: Grant
    Filed: June 11, 2002
    Date of Patent: August 31, 2004
    Assignee: Skyworks Solutions, Inc.

  • Power amplifier with provisions for varying operating voltage based upon power amplifier output power
    Patent number: 6646511
    Abstract: A power amplifier system is disclosed in which a power amplifier unit and a power amendment unit are provided. An operating voltage is applied to the power amplifier unit. The power management unit monitors the current drawn by the power amplifier unit and generates a control signal based upon the measured current. The operating voltage applied to the power amplifier unit is adjusted based upon the control signal.
